CULTIVATOB FENDER.

Application filed November 12, 19226.V Serial No. 148,041.y

The present invention is directed to im proveineiits in a combined weed destroyer and to provide a de-vice of this character so constructed that the weed cut-ting or destroying hoes will elevate and turn the weed bearing earth away from the plants.

Another object of the invention is to provide a device of this kind so constructed that the fenders will protect the small plants in such manner as to prevent them from being covered or broken by the earth turned by the cultivator shovel.

Another' object of the invention is Vto provide fenders capable of yieldable adjustment for use in connection with plants of various heights.

Another object of the invention is to provide a device of this character constructed in such manner that the fenders thereof can be adjusted to bend weeds standing between comparatively tall plants downwardly in order to be effectively covered by earth turned by the cultivator shovels, the yieldable mounting of the fenders permitting the plants to pass therebetween.

Another object of the invention is to provi a device of this character so constructed that the fenders will not only protect the growing plant from being covered or broken by earth thrown up by the cultivator shovels, but can be adjusted for shielding plants of various heights.

In the accompanying drawings:

Figure 1 is a side elevation of a cult-ivator equipped with the fenders. f

Figure 2 is a top plan view thereof.

Figure 3 is a sectional view on line 3-3 of Figure2. c

Figure 4 is al perspective view of one of the fenders removed from the cultivator.

Figure 5 is a sectional view on line 5--5 of Figure 3.

Figure 6 is a sectional side elevation of a slightly modified forni.

Figure 7 is a sectional view on line 7-7 of Figure 6.

Figure 8 is a sectional view on the line 8-8 of Figure 1.

Referring to the drawings, the numeral 1 designates the spaced main beams of a straddle-row cultivator, which have attached thereto beams 2, thel rear ends of which being provided with the cultivator shovels 3, as customary.

fender, and has for its primary objecty I have illustrated my Ainvention as applied to a double gangvcultivator in which instance y a. pair of fendersfare used. It will beof course understood that cultivatorsH having more than two gangs, each gang will .have `associated therewith al fender. i

The fenders 4 are counterpart in construction, therefore a description of yone will suffice for both,and since each fender has associated therewith a yweed cutting hoe, al detail description of the hoe supportingmeans will now be given.

The hoel is fixed to the'rear end of the downturnedend of thefbar 6, said bar terminating at its forward end in a vertical arm 7, which in turn, terminates in a horizontal arm 8, which is secured to the respective beam 1 of the cultivator by a Ubolt 9.

The fender comprises an inverted .yoke 1() formed from strap iron of .suitable gage,

the arms 11 and 12of which being disposed kin true parallel spaced relation. The arm order that the bolt 14, as well asthe bolt 18,

12. The arm 11 is provided with a slot 2O in y can be adjusted to raise or lower the ring 16. This ring is partly closed by a semicircular shield plate 21 which may be secured wit-hin thering .in any suitable manne-r.

The arm 11 carries in additiontothe hook bolts 13. and 14, asimilar bolt 22, the hook of which engages the beam 6, whilegthe shank thereofextends through the slot 20 of the yoke 10, the extended end thereof beingy engaged in the slot 23 ofthe plate 24, said plate having a stop 25. A plate 26 i is carried by the arm 12 of the yoke, the slot 27V thereof being engaged by the pivot bolt 28, said plate being also provided with a stop 29.

[ It will be observed that the plates'are so arranged that the respective stops thereof will be disposed upon lopposite sides of the *ring i 16 in order that the swinging movement thereof will be limited in opposite direc tions, and since the plates 24 and 26 can be adjusted, the swinging movement of the ring can be conveniently regulated.

1n order to connect the beam 6 to one of the beams 2 of the cultivator, a bracket, 30 is employed, said bracket consisting of a bar 5l and an angular member 35, the bar 3l beineT secured to the beam G by a bolt 853. The horizontal bar ot said member is adjustabljtv connected to the bar 3l while the Vertical bar thereot carries a bolt 3G capable of .selectively engagin,r the openings 3T of the bar f5.7, said bolts serving to secure the brackets to the beams 2. The bar is further provided with a plurality of verticall;Y alined perioratiois 3S in order that the hook Si!) carried by the upper end ot the coil spring Alt) can be selectively engaged therein to regulate the tension ot the spring. The lower end ot this spring' is secured to the ring l0 at' a point above the pivot boltll and serves to normally hold said ring; engaged with the stop it) oll the plate titl, in order that its lower portion will be disposed adjacent the row ot` growing plants. Thus, when a straddle-row cultirator is equipped with the tenders the rings will be convergingl)v disposed, as more clearlyv shown in Figure 2 ot the drawings.

It will be obvious that when the cultirator is drawn across a field that the lenders will be so disposed that the plants can pass between the same andthe dirt turned by the shorel will be prevented from passing through the rings and falling,r upon the plants by the shield plate 2l. Since tbe rings are pirotally and yieldably mounted the Yfenders ma)v swing laterally when coming in Contact with the plants' withouty injuring the same. n the modilied form of the invention as shown in Figures tl and T of the drawings, in lieu of the ring,r 1G semicircular lender members Lt1 are used. and since these members are pirotally secured to the `Yoke l0 in the identical manner as the ring. a detailed description is not thoughtv necessary. However. ity will be understood that when these members are used the spring 40 has its lower terminals secured to the member below the pivot; bolts 14, as more clearly shown in Figiue 7 of theA drawings. These members are only used when the plants are comparatively tall and serre to bend the weeds that are lett standing;` in the rows down to thc ground. The plants will slip through the yielding members while the wee l..-fy will be covered by the earth turned by the shovels 3 ofthe cultivalor.

Havingr thus described the invention, I claim:

l. fender of the class deserilied, comprising a vroke. a rin;l pirotallisupported by the yoke, and means for rieldabljt rcstraining the ring against .swinging morement in one direction and holdingr the same in. inclined position with resxert to the yoke.

2. .l fender of the class describtal. com prising a yoke 'or attachment with a culti- Valor. a rin;r pirotall)7 supported between the arms of the Yoke and stops carried by the Aroke for limiting;r the swingingIr movement of the ring.

il. .ik fender ot' the class described com prismer a yoke t'or attachment witlV a culti Valor. a ring' pirotall): mounted between the arm.` ot the yoke. plates adjustably carried by the arms ot the `Yoke and haring stops to limit the swingingI movement of the ring;r in opposite directions. i

el. l'ender of the class described, con1- prisiu; r a yoke for attachment with a cultirator. a rin;lr pirotally supported by the lroke. and means for yieldably sustaining the rin;r in an inclined position with respect to the IYoke.

.t fender of the class described. coinprisiner a -voke, means 'tor adjustably connecting the lYoke with a eultivator. a ring pirotally supported b r and between th? arms of the yoke. plates adjustably carried by the, arms 'oit the yoke and having stops disposed upon opposite sides of the. Yoke for limitiner the swinging movement' of the rim;r in opposite directions. a shield plate carried by the ring'. and ,rieldable meansl for normallyv holdinp; the rin} r in an int-lined position with respeel'Y to the lvoke.

ln testimonx,v whereof l atliX my signature.
